SAN FRANCISCO — Wells Fargo confirmed the Securities and Exchange Commission has launched a probe into a its sales practices linked to bogus bank accounts, and estimated it faces up to $1.7 billion in potential litigation costs linked to an array of problems, according to a new regulatory filing on Thursday.

“Federal, state and local government agencies, including the United States Department of Justice and the United States Securities and Exchange Commission, and state attorneys general and prosecutors’ offices, as well as congressional committees” are among the agencies that have launched inquiries or investigations into the bank’s sales practices, Wells Fargo stated in a filing with the SEC.

The probes involve the mortgage practices of Wells Fargo; a practice by a Wells-purchased bank; Wachovia Bank, related to the order in which debit card transactions are posted to a customer’s account; and Wells Fargo’s sales practices.

The bank’s shares rose slightly in mid-session trades.

San Francisco-based Wells Fargo said it has now set aside nearly twice as much money than it had done so previously to cover its financial exposure to litigation.

“The high end of the range of reasonably possible potential litigation losses in excess of the company’s liability for probable and estimable losses was approximately $1.7 billion as of Sept. 30,” Wells Fargo said in the filing.
